User Manual

Diagnostics <assert.h>

The <assert.h> header declares two macros.

Macros

Character Handling <ctype.h>

The <ctype.h> header declares several macros and functions useful for testing and map-

ping characters. In all cases, the argument is an

int, the value of which is represented as

unsigned char or equals the value of the EOF macro. If the argument has any other

value, the behavior is undefined.

Macros

The above character-handling macros are nonstandard macros.

Functions

The functions in this section return nonzero (true) if, and only if, the value of the argument

c conforms to that in the description of the function. The term printing character refers to

a member of a set of characters, each of which occupies one printing position on a display

device. The term control character refers to a member of a set of characters that are not

printing characters.

NDEBUG The <assert.h> header defines the assert() macro. It refers to the

NDEBUG macro that is not defined in the header. If NDEBUG is

defined as a macro name before the inclusion of this header, the

assert() macro is defined simply as:

#define assert(ignore)((void) 0)

assert(expression); Tests the expression and, if false, prints the diagnostics including

the expression, file name, and line number. Also calls exit with non-

zero exit code if the expression is false.

TRUE Expands to a constant 1.

FALSE Expands to a constant 0.
